Whenever my parents bug me about getting more exercise and loosing weight, I tell them that as soon as I move away to a big city, the pounds will just drop off. Now I have hard data to back me up.
A study recently announced by researchers at the Columbia University Mailman School of Public Health shows a clear link between population density and body mass.
The researchers looked at data from 13,102 adults from New York City’s five boroughs. Matching information on education, income, height, weight and home address with census data and geographic records, they determined respondents’ access to public transit, proximity to commercial goods and services and BMI, a measure of weight in relation to height.
The authors discovered that three characteristics of the city environment – living in areas with mixed residential and commercial uses, living near bus and subway stops and living in population-dense areas – were inversely associated with BMI levels.
